Abstract

The 3D structural information provided by borehole image dips is critical to the accuracy of a reservoir structural model at the wellbore. We explore how to better use borehole dips away from the well. We describe a workflow for extending the borehole dip information away from the well. We base the robustness of the borehole image interpretation on the integration of multiple measurements with various depths of investigation. The results are provided in a 3D near-wellbore structural model. We present an example of a single horizontal well interpretation. The example is a horizontal well drilled in 14-m-thick shoreface sands (Ula formation) of Upper Jurassic age. The structural setting is controlled by halokinesis of underlying Zechstein salt. The 3D near-well structural model is built from the interpretation and structural modelling based on a density image and a deep-reading EM tool.
